Shrub plant named ‘Poultc004’

ABSTRACT

A new garden rose plant of the shrub rose class which has abundant, red flowers, attractive foliage, and abundant rose hips. This new and distinct variety has shown to be uniform and stable in the resulting generations from asexual propagation.

SUMMARY OF THE INVENTION

Botanical classification: Rosa hybrid.

Variety denomination: ‘Poultc004’.

The present invention constitutes a new and distinct variety of garden rose plant that originated from a controlled crossing between the female seed parent, an unnamed seedling, and the male pollen parent ‘Poulerry’, a rose variety by the same inventor, described and illustrated in U.S. Plant Pat. No. 13,450.

The two parents were crossed during the summer of 1996, and the resulting seeds were planted in a controlled environment in Fredensborg, Denmark. The new variety is named ‘Poultc004’.

The new variety may be distinguished from the female seed parent by the following combination of characteristics:

-   -   1. The seed parent has more flower petals than ‘Poultc004’.     -   2. The seed parent is taller in growth habit than ‘Poultc004’.

The new variety may be distinguished from its male pollen parent, ‘Poulerry’ by the following combination of characteristics:

-   -   1. The general tonality of flower color for the pollen parent is         Red Group 53B to 53D while ‘Poultc004’, is Red Group 52A.     -   2. ‘Poulerry’ has more petals than ‘Poultc004’.     -   3. ‘Poulerry’ a larger flower diameter than ‘Poultc004’.

The objective of the hybridization of this rose variety was to create a new and distinct variety for garden use with unique qualities, such as:

-   -   1. Uniform and abundant pink flowers;     -   2. Vigorous, but compact growth when propagated both as a budded         rose and on its own roots;     -   3. Exceptional disease resistance.

This combination of qualities is not present in previously available commercial cultivars of this type, known to the inventor, and distinguish ‘Poultc004’ from all other varieties of which we are aware.

As part of the rose development program, Mogens N. Olesen germinated the seeds from the aforementioned hybridization during winter of 1996 and conducted evaluations on the resulting seedlings in a controlled environment in Fredernsborg, Denmark.

‘Poultc004’ was selected in the spring of 1997 by the inventor as a single plant from the progeny of the aforementioned hybridization.

Asexual reproduction of ‘Poultc004’ by traditional budding and rooted cuttings was first done by Mogens N. Olesen in the nursery in Fredensborg, Denmark in July 1997. This initial and other subsequent asexual propagations conducted in controlled environments have demonstrated that the characteristics of ‘Poultc004’ are true to type and are transmitted from one generation to the next.

DETAILED DESCRIPTION OF THE VARIETY

The following is a description of ‘Poultc004’, as observed in its growth in a field nursery in Jackson County, Oreg. Observed plants are 2 years of age, and were grown on Rosa multiflora understock. Color references are made using The Royal Horticultural Society (London, England) Colour Chart, 2001, except where common terms of color are used.

For a comparison, several physical characteristics of the rose variety ‘Poultw001’, a rose variety from the same inventors described and illustrated in U.S. Plant Pat. No. 15,111 issued Aug. 24, 2004, are compared to ‘Poultc004’ in Chart 1.
